home_url returns url with wrong scheme

[Gerkin]

Hello,

I have a multisite with HTTPS on all subsites. When using

home_url( '/' );

, on a subsite page, logged in user got a https url, when anonymous got just http.

In the track, it seems that the error comes from those lines...

2963            if ( ! in_array( $scheme, array( 'http', 'https', 'relative' ) ) ) {
2964                    if ( is_ssl() && ! is_admin() && 'wp-login.php' !== $pagenow )
2965                            $scheme = 'https';
2966                    else
2967                            $scheme = parse_url( $url, PHP_URL_SCHEME );
2968            }

...

Thank you for your time.

Thanks for the report, @Gerkin.

How are you implementing HTTPS on your site? WordPress core doesn't vary the home URL scheme depending on whether or not a user is logged in, so there must be something else affecting its return value, such as a plugin on your site that's filtering the value.

• How are you implementing HTTPS URLs on your subistes?
• Do you have a plugin on your site which is filtering the home URL return value?
• Are you using domain mapping?

Hello,
I'm using the plugin "WordPress HTTPS" to force all URLs become SSL encrypted. wp-config.php was also modified to enable SSL.

What do you mean by "Domain mapping"?

Thank you
